Collectors and Promoters

Comments Off

Nowata purchase various xanthates from manufacturers in both South Africa and the Far East. As well as the standard xanthate homologues of ethyl, propyl, butyl and amyl, Nowata supply mixed xanthates in conjunction with other collectors.

As well as xanthates which are still used as the primary collector in most mines we have a range of dithiophosphates, dithiocarbamates, xanthogen formates and xanthic esters. We have developed a customized range of blended products which have application in the gold, base metal and platinum industries and have been shown to give improved recoveries particularly where rapid oxidation may occur. These blended products have been shown to be capable of replacing both primary and secondary collectors.
